The Countess of Mar asked Her Majesty's Government:
The Parliamentary Secretary, Ministry of Agriculture, Fisheries and Food (Lord Donoughue): BSE infected brain homogenate was fed in a raw state to calves at the Central Veterinary Laboratory, Weybridge, in the course of research into BSE.
The Countess of Mar asked Her Majesty's Government:
Lord Donoughue: The calves used in the Pathogenesis Study of BSE at the Central Veterinary Laboratory were sourced from 12 farms with no history of confirmed cases of BSE. Apart from the requirement that the calves were Friesian/Holstein and male, no other specific selection criteria were applied because it was not possible (or desirable) to source all the calves for one experiment from a single farm and not possible therefore to control all variables. Consequently, calves are allocated to challenge and control groups in the experiment in a random manner to eliminate bias as a result of influences determined by the source farm.
The Countess of Mar asked Her Majesty's Government:
Lord Donoughue: Forty calves were used in the study of the Pathogenesis of BSE at the Central Veterinary Laboratory, Weybridge. All available interim results of their ages at slaughter and the demonstration of infectivity in their tissues are published (Wells et al 1998 Veterinary Record 142, 103-106) and further details of infectivity in tissues of these cattle will be published when available.
The Countess of Mar asked Her Majesty's Government:
Lord Donoughue: The following table lists the total number of cattle in Great Britain which have been diagnosed as suffering from BSE from 1986 to 4 February 1998. The cattle are shown by breed, including crossbreed. There are no records kept centrally of BSE cases indicating the breed of the dam.

The Countess of Mar asked Her Majesty's Government:
Lord Donoughue: The following table shows the total incidence of BSE for each county in the United Kingdom from 1986 to 1997 inclusive.
Lord Lucas asked Her Majesty's Government:
Further to the remarks of the Chief Medical Officer (CMO) quoted by Lord Donoughue on 27 January (H.L. Deb., Col. 150), whether the CMO would have modified his advice on the necessity of de-boning beef if the Spongiform Encephalopathy Advisory Committee's (SEAC) estimate of the most likely number of infected animals entering the food chain in 1998 had been (a) two; (b) one; or (c) none (all other things being equal); and, if so, what such modified advice would have been.[HL369]
Lord Donoughue: The Chief Medical Officer (CMO) bases his advice to Ministers on the available evidence, rather than theoretical speculation.
On this occasion, BSE infectivity had been found in the dorsal root ganglia and bone marrow, tissue not covered by regulations preventing it from entering the human food chain. The CMO has consistently taken the view that it would be wrong to knowingly allow material which might contain BSE infectivity to enter or remain in the human food chain.
Minsters accepted that the risk of contracting new variant Creutzfeldt-Jakob disease from exposure to this material, although very small, was real. Because the protection of public health is a priority for this Government, we decided that action was necessary to ensure that material that could convey infectivity was removed from the human food chain.
